I have a sorceress in a recently started RotrL with the Impossible bloodline. Being a gearhead from background i'm going to have her make constructs when she's at higher levels. She gets bonus feats connected to crafting.
Would the AP have more use of constructs being clockwork or golems?
It's actually fun to get it early and tinker around with some of the cheaper constructs. A throwaway Homunculus actually makes for a really fun scout and you'll laugh hysterically if he ever puts the bite on someone. I don't think it'll make a difference either which types you build as they're all quite fun.
Not sure what you mean by construct armor, but your Sorceress will do just fine with a +1 Guardian Haramaki one you can either afford to purchase/make it.
